1 Includes amplifier voltage and current noise, as well as noise of internal resistors.
2 dBu = 20 log (V rms/0.7746).
3 Includes input bias and offset current errors.
4 May also be limited by absolute maximum input voltage or by the output swing. See the Absolute Maximum Ratings section and Figure 9 through Figure 12 for
details.
5 Internal resistors are trimmed to be ratio matched but have ±20% absolute accuracy.
6 Common mode is calculated looking into both inputs. Common-mode impedance looking into only one input is 18 kΩ.
